PROPELLER-WHEEL.

Specification of Letters Patent.

Patented Mar. 30, 1915.

To all whom it may concern Be it known that I, EUGENE BELIGZA, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Propeller- Wheels, of which the following is a specification.

My invention relates to propeller wheels, and more particularly to that type thereof generally known as feathering propeller wheels wherein the blades, during rotation thereof, are feathered at one side of the wheel so as to reduce resistance.

The object of my invention is the production of a propeller wheel as mentioned which will be of simple construction and eliicient in operation.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawing forming a part of this specification, and in which,

Figure 1 is a substantially central section of a propeller wheel embodying my invention, Fig. 2 is a section taken on line w-w of Fig. 1, and Fig. 3 is an enlarged fragmentary detail section taken on line y-y of Fig. 2.

The preferred form of construction as illustrated in the drawing comprises a shaft 1 which is fixed to a suitable support 2, the latter, when the propeller wheel is in use, being a part of the frame work of the machine or vessel in conjunction with which the wheel is employed, as will be readily understood. Rotatably mounted upon the shaft 1 is a collar 3, the same being held against longitudinal movement upon said shaft by stop collars 1. Secured to one end of the collar 3 is a bevel gear 5 with which meshes a second gear 6, the latter, during the operation of the propeller wheel, being connected for driving with the motor or other source of power supply carried by the machine or vessel upon which the propeller wheel is used.

Provided at the lower end of collar 3 are outwardly projecting diametric pins 7 upon which is rockingly mounted midway its ends a blade carrier 8. The latter is elongated in form and the central portion thereof is cut away as shown in order to permit of oscillation of said carrier without striking the collar 3 or shaft 1. I

Provided at the respective ends of carrier 8 are rollers 9 which contact with an annular irregular .cam surface 10 formed at the upper side of a cam member 11. The cam surface 10 is of such formation that, during rotation of the collar 3 and hence the car rier 8, the latter will be oscillated during such rotation, the amplitude of oscillation being substantially ninety degrees and such oscillation occurring once in each complete rotation of said carrier.

Formed integral with and projecting outwardly from the carrier 8 in alinement with the axis of oscillation thereof are diametric lugs 12 from which project propeller blades 13. The inner ends of said propeller blades are secured to the lugs 12 by means of angular plates 14L, the respective ends of which are secured to said blades and lugs by screws 15, the portions engaged by said plates being angular in cross section in order to accommodate and engage nicely with the ends of said plates. A rigid connection between the carrier and the propeller blades is thus secured.

With the arrangement set forth, it will be seen that during rotation of the propeller blades, the same will also be oscillated so as to effect feathering thereof during substantially half of each rotation. Said blades are arranged at right angles to each other so that when one is in operative position, the other will be in feathering position, the blades being in operative position only when moving in the direction in which the same will drive the vessel upon which the propeller wheel is used, in the desired direction.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. 1, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having described my invention what I claim as new and desire to secure by Letters Patent is:

1. In mechanism of the character described, the combination of a shaft; an element mounted upon said shaft for rotary and rocking movement, the rocking move ment being in a plane perpendicular to the plane of rotary movement of said element; a cam surface cooperating with opposite ends of said element for effecting rocking movement thereof upon rotation of said element; and a pair of diametric blades fixed to said element so as to be rocked thereby during rocking movement of the latter, substantiall as described. V

2. Inmechanism of the character described, the combination of a shaft; a blade carrier mounted upon said shaft for rotary and oscillatory movement, the oscillatory movement being in a plane perpendicular to the plane of rotary movement of said element; a cam surface; diametric rollers on said carrier engaging with said cam surface for effecting oscillatory movement of said cutter upon rotation thereof; and a pair of diametric blades fixed to said carrier so as to be oscillated thereby during oscillatory movement of the latter, substantially as described. i

3. In mechanism of the character described, the combination of a shaft; a blade carrier mounted upon and oscillatory movement, the oscillatory movement being in a plane perpendicular to the plane of rotary movement of said elemerit; a cam surface; diametric rollers on said carrier engaging with said'cam surface for effecting oscillatory movement of said carrier upon rotation thereof; and a pair of diametric blades fixed to said carrier and projecting therefrom in alinement with the axis of oscillation of said carrier, substantially as described. j

4. In mechanism of the character describe the combination of a shaft; an elongated carrier mounted midway its ends upon said shaft for rotary and oscillatory movement, the oscillatory movement being in a plane perpendicular to the plane of rotary movement of said element; an annular cam surface; rollersprovided at the ends of said carrier engaging with said cam surface for effecting oscillatory movement of said carrier upon rotation thereof; and a pair of diametmc blades fixed to said carrier and extending therefrom in alinement with the axis of oscillation of said carrier, substan tially as described.

5 In mechanism of the character describe the combination of a shaft; an elonsaid shaft for rotarygated carrier mounted midway its ends upon said shaft for rotary and oscillatory move ment, the oscillatory movement being in a plane perpendicular to the plane of rotary movement of said element; an annular cam surface; rollers provided at the ends of said carrier engaging with said cam surface for effecting oscillatory movement of said carrier upon rotation thereof; outwardly projecting diametric lugs formed upon said carrier in alinement with the axis of rotation thereof; and outwardly projecting blades havingtheir inner ends fixed to said lugs, substantially as described. 7

6. In mechanism of the character described, the combination of a shaft; an elongated carrier mounted midway its ends upon said shaft for rotary and oscillatory movement, the oscillatory movement being in a plane perpendicular to the plane of rotary movement of said element; an annular cam surface; rollers provided at the ends of said scribed, the combination of a shaft; a collar' rotatably mounted upon said shaft;,a pair of outwardly projecting diametric pins'on said collar; a blade carrier rockingly mounted midway its ends upon saidpins; an an-' nular cam surface; rollers at the ends of said carrier engaging said cam surface whereby, upon rotation of said collar, said carrier will be simultaneously oscillated; and diametric blades secured at their inner ends to said carrier and projecting therefrom in alinement with the axis of oscillation of said carrier, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
